The support ear is made from at least one overlapping, heat-resistant film (4). A cable sheath (6) is arranged on the tube.

Description

Die Erfindung bezieht sich auf ein optisches KabeL gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an optical cable according to the preamble of claim 1.

Aus der DE-PS 30 02 498 ist ein Nachrichtenkabel mit mehreren LichtweLLenLeitern bekannt, die je eine primäre und eine sekundäre Beschichtung aufweisen und die miteinander um ein zentrales Element zu einem Verbund verseilt sind. Um den verseilten Verbund ist eine HaltewendeL gelegt, die den Verbund zusammenhalten soll. Da die Haltewendel fest auf den Lichtwellenleitern aufsitzt, besteht die Gefahr, daß auf diese Kräfte ausgeübt und sie mechanisch beansprucht werden. Um eine Deformation der LichtweLLenLeiter zu vermeiaen, ist das Nachrichtenkabel mit einer FüLLmasse gefüllt, die den Stoff der Haltewendel erweicht oder ihn zerfallen Läßt, so daß nur während der HersteLLung des Nachrichtenkabels die Haltewendel Kräfte auf die LichtweLLenLeiter ausübt.From DE-PS 30 02 498 a communication cable with several optical waveguides is known, each having a primary and a secondary coating and which are stranded together to form a central element to form a composite. A holding turn is placed around the stranded composite, which is intended to hold the composite together. Since the helix is firmly seated on the optical fibers, there is a risk that these forces are exerted and mechanically stressed. In order to avoid deformation of the optical waveguide, the communication cable is filled with a filling compound which softens the material of the holding spiral or causes it to disintegrate, so that the holding spiral exerts forces on the optical waveguide only during the production of the communication cable.

Bekanntlich strahlt jeder dielektrische Wellenleiter, so- .bald seine Achse von einer Geraden abweicht. Die StrahLung hängt sehr vom Krümmungsradius ab und steigt von vernachLässigbar kleinen Werten schnell auf nicht mehr vertretbare Verluste an. Bei monomodaten Lichtwettenteitern kommt noch die nachteilige Beeinflussung der Grenzwellenlänge von Moden verschiedener Ordnung hinzu.As is known, every dielectric waveguide radiates as soon as its axis deviates from a straight line. The radiation depends very much on the radius of curvature and rises quickly from negligibly small values to unacceptable losses. In the case of monomode light betting tubes, there is also the disadvantageous influence on the cutoff wavelength of modes of different orders.

Der Erfindung Liegt die Aufgabe zugrunde, ein optisches Kabel anzugeben, bei dem nicht nur die aus dem Kabelaufbau kommenden Kräfte aufgehoben, sondern auch von außen einwirkende Kräfte von den Lichtwellenleitern ferngehalten werden.The invention is based on the object of specifying an optical cable in which not only the forces coming from the cable structure are eliminated, but also forces acting from outside are kept away from the optical fibers.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Mittel gelöst. AusgestaLtungen können den Unteransprüchen entnommen werden.This object is achieved by the means specified in claim 1. Exhibitions can be found in the subclaims.

Beim erfindungsgemäßen optischen KabeL werden durch das im Abstand zu den Lichtwellenleitern vorhandene Stützrohr die von außen kommenden radial wirksamen Kräfte abgefangen. SoLche Kräfte entstehen entweder bereits bei der HersteLLung des KabeLmanteLs oder sie treten zusätztich beim UmtrommeLn oder Verlegen der KabeL auf. Da der innerhatb des Stützrohrs gelegene Verbund der Lichtwellenleiter nicht mit einer Bebänderung, BewickLung oder einer Wendel versehen ist, kann/können sich der/die LichtweLLenLeiter frei expandieren und damit einen kräftefreien Verbund bilden.In the optical cable according to the invention, the radially effective forces coming from outside are intercepted by the support tube which is at a distance from the optical waveguides. Such forces either arise during the manufac- ture of the cable or they also occur when the cable is rewound or relocated. Since the composite of the optical waveguide located inside the support tube is not provided with a strap, winding or a helix, the optical waveguide (s) can expand freely and thus form a force-free composite.

Es ist anzumerken, daß es aus der DE-PS 30 10 353 für ein optisches übertragungselewent bekannt ist, eine Faser eines Lichtwellenleiters Lose im Innern einer aus Innen und AußenhüLLe zusammengesetzten UmmanteLung anzuordnen. Diese Anordnung ist auch als HohLader bekannt. Die InnenhüLLe besteht hierbei aus einer oder mehreren mit SchLag gewickelten FoLien, auf die die AußenhüLLe aufgespritzt ist.It should be noted that it is known from DE-PS 30 10 353 for an optical transmission element to arrange a fiber of an optical waveguide loosely in the interior of a sheath composed of an inner and outer shell. This to order is also known as HohLader. The inner shell consists of one or more foils wrapped with impact, onto which the outer shell is sprayed.

Die Erfindung wird nun anhand von Zeichnungen zweier Ausführungsbeispiele näher erläutert. Es zeigen:

  • Fig. 1 einen Querschnitt einer ersten Ausführung eines optischen KabeLs;
  • Fig. 2 ein abgesetztes Ende des KabeLs gemäß Fig. 1;
  • Fig. 3 einen Querschnitt einer zweiten Ausführung eines optischen KabeLs und
  • Fig. 4 ein abgesetztes Ende des KabeLs gemäß Fig. 3.
The invention will now be explained in more detail with reference to drawings of two exemplary embodiments. Show it:
  • 1 shows a cross section of a first embodiment of an optical cable;
  • FIG. 2 shows a stepped end of the cable according to FIG. 1;
  • Fig. 3 shows a cross section of a second embodiment of an optical cable and
  • 4 shows a stepped end of the cable according to FIG. 3.

Das in Fig. 1 dargestellte optische KabeL weist ein zentraLes ELement 1 auf, das aLs zugfestes ELement ausgebildet sein kann und dann hierzu aus GLasfasergarn besteht. Auf das ELement 1 sind sechs LichtweLLenLeiter 3 und zwei Blindelemente 2 verseilt. Die Anzahl der LichtweLLenLeiter 3 und der Blindelemente 2 ist nur als Beispiel anzusehen, es ist auch jede andere AnzahL von LichtweLLenLeitern 3 ohne oder mit den entsprechenden BLindeLementen 2 möglich. Die LichtweLLenLeiter 3 sind primär und sekundär beschichtete LichtweLLenLeiter. Die als FüLLer wirkenden BLindeLemente 2 weisen den gleichen Durchmesser wie die LichtweLLenLeiter 3 auf und bestehen beispielsweise aus Polyamid. Dieser so gebildete Verbund aus dem zentralen ELement 1 und den LichtweLLenLeitern 3 und Blindelementen 2 ist frei beweglich in einem flexiblen Stützrohr angeordnet.The optical cable shown in FIG. 1 has a central element 1, which can be designed as a tensile element and then consists of glass fiber yarn for this purpose. Six lightwave conductors 3 and two blind elements 2 are stranded on the element 1. The number of light waveguides 3 and the dummy elements 2 is only to be seen as an example; any other number of light waveguides 3 without or with the corresponding blind elements 2 is also possible. The optical waveguide 3 are primary and secondary coated optical waveguide. The blind elements 2, which act as fillers, have the same diameter as the optical waveguide 3 and consist, for example, of polyamide. This combination of the central element 1 and the optical waveguides 3 and dummy elements 2 is freely movable in a flexible support tube.

Das flexible Stützrohr besteht aus einer temperaturbeständigen FoLie 4 und einer temperaturbeständigen DeckfoLie 5. Die innere FoLie 4 ist im nicht gewickelten Zustand biegesteif, etwa 75 µm dick und besteht aus Polyäthytenterephthalat (PETP). Sie ist im Gegenschlag zum Verbund überlappt gewickelt und bildet so das flexible Stützrohr. Die SchLagLänge ist dabei kleiner aLs der zehnfache Durchmesser des Verbundes. Die Schlaglänge kann gleich der zweifachen Breite der Folie 4 entsprechen. Dabei stellt sich eine ausreichende überlappung ein. Auf diese innere Folie 4 kann bereits ein KabeLmanteL angeordnet werden. Um zu verhindern, daß das aus der Folie 4 gewickelte Stützrohr aufgrund der an sich biegesteifen FoLie aufspringt, ist darüber die Deckfolie 5 gewickelt.The flexible support tube consists of a temperature-resistant FoLie 4 and a temperature-resistant cover foil 5. The inner FoLie 4 is non-coiled, about 75 µm thick and made of polyethylene terephthalate (PETP). In contrast to the composite, it is overlapped and thus forms the flexible support tube. The lay length is smaller than ten times the diameter of the composite. The lay length can equal twice the width of the film 4. There is sufficient overlap. A cable cover can already be arranged on this inner film 4. In order to prevent the support tube wound from the film 4 from springing open due to the inherently rigid film, the cover film 5 is wound over it.

Die DeckfoLie 5 besteht aus einem 0,4 mm dicken SchaumLaminat aus Polyäthylenterephthatat (PETP). Sie ist im 6e-genschLag zur FoLie 4 auf diese gewickelt. Die Schtaglänge ist dabei so gewählt, daß eine BewickLung auf Stoß oder eine geringfügige uberlappung entsteht. Die FoLie 5 deckt gleichzeitig die SpaLten der FoLie 4 ab, so daß bei der Aufbringung eines während des Aufbringens plastischen oder flüssigen Kabelmantels kein Material von diesem in das Stützrohr und eventueLL an die LichtweLLenLeiter gelangt.The cover sheet 5 consists of a 0.4 mm thick foam laminate made of polyethylene terephthalate (PETP). It is wrapped on FoLie 4 in 6-fold. The length of the pile is selected in such a way that there is winding on the joint or a slight overlap. The FoLie 5 simultaneously covers the columns of the FoLie 4, so that when a plastic or liquid cable sheath is applied during the application, no material from it gets into the support tube and possibly to the fiber optic cable.

Der KabeLmanteL (6) enthält zugfeste ELemente, die beispielsweise aus parallel Laufenden Fäden, einem Geflecht 7 oder einem Gitternetzband bestehen. Der KabeLmanteL ist direkt auf dem Stützrohr aus den FoLien 4 und 5 aufgebracht.The KabeLmanteL (6) contains tensile elements, which consist, for example, of threads running in parallel, a braid 7 or a grid belt. The cable is attached directly to the support tube made of foils 4 and 5.

In Fig. 2 ist ein Ende des in Fig. 1 dargestellten optischen KabeLs gezeigt, bei dem der KabeLmanteL 6 und die darunter Liegenden TeiLe des KabeLs teilweise entfernt sind. Es ist zu erkennen, daß die FoLie 5 auf Stoß und die FoLie 4 überlappt gewickeLt ist und die LichtweLLenLeiter 3 und die Folien jeweils im GegenschLag gewickelt sind.FIG. 2 shows one end of the optical cable shown in FIG. 1, in which the cable part 6 and the parts of the cable underneath are partially removed. It can be seen that the film 5 is wound in an abutting manner and the film 4 is overlapped and the light waveguide 3 and the films are each wound in a counter-lay.

In Fig. 3 ist eine weitere Ausführung eines optischen KabeLs im Querschnitt dargestellt. Die Mikrokrümmungsempfindlichkeit optischer KabeL hängt neben ihrem Aufbau entscheidend vom thermischen Ausdehnungskoeffizienten des gesamten KabeLaufbaus ab. Da optische KabeL im wesentlichen aus Kunststoff mit einem relativ hohen Ausdehnungskoeffizienten bestehen, ist zur Verbesserung der Tieftemperatureigenschaften ein besonderer Aufbau zu wählen. NachfoLgend wird ein metallfreies, Leichtes KabeL beschrieben, das nicht durch elektrische FeLder beeinflußt werden kann und das eine hohe Blitzsicherheit.aufweist. Dessen Verbund besteht aus zwei LichtweLLenLeitern 3, die zusammen mit zwei BLindeLementen 2 um ein zentraLes ELement 1 mit einem SchLag verseilt sind. Das zentrale ELement 1 dient hierbei LedigLich aLs GrundLage zum Verseilen. Das darüber im Abstand angebrachte Stützrohr besteht wieder aus den beiden FoLien 4 und 5. In diesem FaLLe ist auch die Deckfolie 5 überlappt gewickeLt. Der KabeLmanteL 8 besteht bei dieser Ausführung aus einem gehärteten Harzsystem als Matrix mit darin eingebetteten und davon durchtränkten, orientierten Verstärkungsfasern als Armierung. Darüber ist eine Schutz hülle 9 angeordnet, die z. B. aus PoLyäthyLen (PE) bestehen und mit Ruß versetzt sein kann.3 shows a further embodiment of an optical cable in cross section. The micro-curvature sensitivity of optical cables depends not only on their structure, but also on the thermal expansion coefficient of the entire cable structure. Since optical cables essentially consist of plastic with a relatively high coefficient of expansion, a special design should be chosen to improve the low-temperature properties. A metal-free, light cable is described below, which cannot be influenced by electrical fields and which has high lightning protection. Its composite consists of two optical waveguides 3, which are stranded together with two blind elements 2 around a central element 1 with one lay. The central element 1 only serves as the basis for stranding. The support tube attached above it at a distance again consists of the two foils 4 and 5. In this case, the cover foil 5 is also overlapped. In this version, the KabeLmanteL 8 consists of a hardened resin system as a matrix with oriented reinforcing fibers embedded in it and saturated with it as reinforcement. In addition, a protective cover 9 is arranged, the z. B. from PoLyäthyLen (PE) and may be mixed with soot.

In Fig. 4 ist ein Ende des in Fig. 3 dargestellten KabeLs gezeigte bei dem die SchutzhüLLe 9 und die darunterliegenden TeiLe des KabeLs teilweise entfernt sind. Es ist ersichtlich, daß die Lichtwettenteiter 3 und die BLindeLemente 2 mit einem SchLag verseilt, die FoLien 4 und 5 überLappt gewickelt und alle diese drei Teile im Gegenschlag zueinander aufgebracht sind.FIG. 4 shows one end of the cable shown in FIG. 3, in which the protective sheath 9 and the parts of the cable underneath are partially removed. It can be seen that the light betting ladder 3 and the blind elements 2 are twisted with one lay, the foils 4 and 5 are wrapped overlapped and all these three parts are applied in counter-lay to one another.

Es kann auch ein Verbund aus einem oder mehreren nicht verseilten LichtweLLenLeitern gewähtt werden, in dem LängsLaufende Fäden ohne Verseitschlag als ZugeLemente angeordnet sind.A composite of one or more non-stranded optical waveguides can also be selected, in which longitudinal threads are arranged as tension elements without a side lay.

Die Herstettung des Stützrohrs aus mindestens einer überLappt gewickelten temperaturbeständigen FoLie geschieht zweckmäßigerweise gleichzeitig mit dem Herstellen des Verbundes . Hierzu werden ein oder mehrere schnellaufende Zentralspinner eingesetzt, durch welche eine hohe Fertigungsgeschwindigkeit erzielt werden kann. Zum Aufbringen des Stützrohrs können die tentratspinner mit einem stimmgabelförmigen Wickeldorn versehen sein.The production of the support tube from at least one overlapped, temperature-resistant film is expediently carried out simultaneously with the production of the composite. For this purpose, one or more high-speed central spinners are used, through which a high production speed can be achieved. To attach the support tube, the center spinner can be provided with a tuning fork-shaped winding mandrel.
